Who qualifies
To get Hydroquinone online in Leganés, you must be an adult dealing with diagnosed or suspected melasma. Hi-Doctor’s dermatology pathway covers topical melasma care for suitable candidates:
- Eligible condition: Facial melasma (epidermal or mixed pigmentation).
- Available topical formulary: Hydroquinone 4% cream (such as HQUIN), Hydroquinone 4% gel (such as Licoforte), or a compounded melasma formula containing hydroquinone 4% + tretinoin 0.025% + kojic acid 2% + niacinamide 4%.
- Clinical exclusions: Pregnant or breastfeeding individuals, patients with active skin infections, or suspected suspicious pigmented lesions (which require in-person biopsy).
- In-person referrals: Severe, nodular, cystic, or scarring skin conditions, as well as requests for oral isotretinoin or oral antibiotics, are referred to in-person care. Hi-Doctor prescribes topical treatments only.
What Hydroquinone actually does
Hydroquinone is a direct tyrosinase inhibitor. It functions by inhibiting the enzymatic conversion of dihydroxyphenylalanine (DOPA) to melanin within epidermal melanocytes, decreasing overall pigment production in hyperactive areas.

Depigmentation is a gradual process that requires defined treatment cycles rather than indefinite application. Most clinical protocols observe visible lightening between 4 and 12 weeks of nightly use. Because melasma is exacerbated by ultraviolet and visible radiation, daily application of broad-spectrum SPF 50+ is mandatory; tinted formulations containing iron oxides provide additional protection against visible light wavelengths that standard mineral filters do not block.
| Treatment Option | Active Ingredients | Application Protocol | Primary Indication |
|---|---|---|---|
| Hydroquinone 4% Cream | Hydroquinone 4% | Nightly to pigmented lesions | Localized epidermal melasma |
| Hydroquinone 4% Gel | Hydroquinone 4% | Nightly (lighter base) | Melasma on oily or combination skin |
| Compounded Formula | HQ 4% + Tretinoin 0.025% + Kojic 2% + Niacinamide 4% | Nightly under medical guidance | Moderate to severe or resistant melasma |
Side effects and when to stop
Topical depigmenting agents can cause localized skin reactions. Knowing what to expect ensures safe treatment:
- Expected mild effects: Mild redness (erythema), temporary dryness, localized peeling, and mild transient stinging during initial weeks.
- When to discontinue: Intense burning, severe contact dermatitis, blistering, or spreading erythema require immediate cessation and medical review.
- Long-term considerations: Unsupervised, continuous use over extended months increases the risk of exogenous ochronosis (a rare bluish-black paradoxical pigmentation). For this reason, doctors prescribe Hydroquinone in structured courses, typically lasting up to 3 to 4 months.
